DESCRIPTION OF THE EMBODIMENTS

To understand the technical characteristics of this disclosure intuitively and comprehensively, exemplary embodiments are used and illustrated in referenced figures of the drawings. It is intended that the embodiments and figures disclosed herein are to be considered illustrative rather than restrictive.

Embodiment 1

With reference to FIGS. 1 to 4 for a dual-extrusion electronic cigarette of this embodiment, the dual-extrusion electronic cigarette comprises a housing 1 and a dual-extrusion structure installed in the housing 1, and the dual-extrusion structure comprises an atomizer seat 2, a tee tube 3, three conduits 4 and two oil bottles, and a positive electrode core 5 is coupled to the bottom of the atomizer seat 2 and insulated from the atomizer seat 2, and the positive electrode core 5 is a hollow structure, with a lower end communicated to the tee tube 3 through the conduit 4, and the two oil bottles are coupled to the tee tube 3 through the conduit 4, and the oil bottle is a soft bottle.

Since the oil bottle is a soft bottle, the interior of the oil bottle will be deformed when a user's fingers squeeze and press the oil bottle, so that a cigarette oil can be squeezed out from the oil bottle and passed through the connected positive electrode core 5, the conduit 4 and the tee tube 3, so that the cigarette oil of the two oil bottles can be collected into the atomizer connected to the atomizer seat 2, and then the cigarette oil can be atomized into vapor and mist.

In this embodiment, a dual-channel tube 6 is coupled between the oil bottle and the conduit 4, and the external diameter of both ends of the dual-channel tube 6 is smaller than the external diameter of the middle of the dual-channel tube 6, and both ends of the dual-channel tube 6 are inserted into the conduit 4 and the oil bottle respectively.

The structure with both finer ends and a thicker middle allows the dual-channel tube 6 to be inserted into the conduit 4 and the oil bottle to ensure the stability of the connection of both ends.

In this embodiment, the oil bottle comprises a bottle body 8, a cap 7, and a hose 9, and the bottle body 8 has a bottle opening formed thereon, and the cap 7 is sheathed on the outer side of the bottle opening, and the cap 7 has a cap opening formed thereon, and the hose 9 penetrates through the cap opening, and the external diameter of the hose 9 is equal to the diameter of the cap opening, and the hose 9 has an end extended to a bottle bottom of the bottle body 8 and the other end sheathed on the dual-channel tube 6.

Since the hose 9 is extended directly to the bottom of the bottle body 8, therefore the bottommost cigarette oil can be pumped out to prevent unnecessary waste when the oil bottle is pressed and squeezed.

In this embodiment, the atomizer seat 2 is disposed on an upper end surface of the housing 1, and two grooves are formed at a lower end of the housing 1, and one of the oil bottles is installed into one of the grooves, and an outer cover is installed on a side of the housing 1, and a receiving cavity is formed between the outer cover and the housing 1, and the bottle body 8 is disposed in the receiving cavity.

The outer cover and the housing 1 are configured to be separated from each other to facilitate a user's hand to squeeze or press the outer cover in order to squeeze or press the oil bottle fixed in the housing 1.

In this embodiment, the outer cover is a fully-covering outer cover 10 with a lower end depressed towards the housing 1 and an upper end having an anti-slip pattern 12 disposed thereon.

Therefore, the fully-covering outer cover 10 looks more beautifully.

In this embodiment, the outer cover has an upper concave hole 13 formed at an upper end of the outer cover and a lower concave hole formed at a lower end of the outer cover, and a magnet is installed in the upper concave hole 13, wherein the magnet has an upper end magnetically coupled to the housing 1 and a lower end magnetically coupled to the outer cover, and the housing 1 has a pillar 14 disposed thereon and inserted into the lower concave hole.

By attaching the magnet to the outer cover and the housing 1, the outer cover can be prevented from falling out, while the pillar 14 and the lower concave hole are provided for limiting the extent of squeezing or pressing.
